PAINT-Mm..

SPECIFICATION forming part of Letters Patent No. 531,824, dated January 1, 1895.

Application led March 20, 1894. Serial Noi 504,429. (No modeh) To a/ZZ whom, it may concern:

Be it known that I, CARL P. ANDERSON, `of Everett,in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Paint-Mills, of which the following is a specification.

This invention relates to paint mills and the object is to provide `means for more advantageously treating the paint, both in feed ing it to the mill and in delivering it therefrom,

To this end the invention consists in certain novel features of construction and combinations of parts pointed out in the appended claims and specilically described in the following specification.

The accompanying drawings which form part of the specification illustrate a construction embodying the invention.

Of the drawings-Figure l shows a side elevation of a paint mill having my improve ments. Fig. 2 shows a top plan view on an enlarged scale of the cooling apparatus. Fig. 3 shows avertical central section of the cooling apparatus, Fig. d shows a' perspective detail of a funnel through which the paintis supplied to the mill said funnel being repref sented as broken away to disclose parts inclosed within it.

lt has been the practice heretofore to supply the hopper of the mill with the paint en masse, and this has been found objectionable for the reason that the paint is inclined to settle, and to feed to the mill with its ingredients not properly intermixed.

One feature of my invention resides in means for regulating the feed of the paint so that it may be supplied to the mill only in proportion as it is disposed of thereby. The devices illustrated in the drawings for accomplishing this object comprise a funnel, h, depending from the supply pipe, c, over the hopper, a, of the mill, and having an outlet opening, b', formed in one side, and a gate, b2, at one side of said opening and controlling the egress of the paint therethrough. The volunie of the stream of paint issuing from the opening, b', is regulated by means of the gate, b2, in accordance with the capacity of the mill, and therefore, the paint does not collect in the hopper, a, as heretofore, but the latter simply serves to conduct the paint into the extends over the disk, fm, and the paint carv ried around by said disk encounters said fixed arm, 1712, and is thus agitated and kept properly mixed. The shaft, m, carries affixed to it at its upper end a stirrer blade or arm, m3,

which also agitates the paint in the funnel.

Heretofore the paint has been taken directly from the mill into the barrels, kegs or other receptacles in which it is to be stored, and is still hot when delivered to such receptacles. This is objectionable for many reasons, and it is highly desirable that the-paint be cooled before illing the receptacles with it.

My linvention provides means for expeditiously cooling the paint as it issues from the mill and before it is delivered to the barrels, casks, or other receptacles. The paint passes from the mill onto a chute, d, which conducts it into a basin or receptacle, e, of annular form having a central standpipe, e', and a conical bottom, e2. This receptacle, e, is surrounded by a water jacket, f, which is a receptacle of similar form to the receptacle, e, having a central stand-pipe, f', which extends up into the stand-pipe, e', a suitable space being left for the water. The receptacle, e, is provided with feet, e3, which rest on the bottom of the receptacle, f, and provide a space between the bottoms of the two receptacles for the water. The water is fed into the jacket, f, through a supply-pipe, g, which enters the lower portion of the same and rises around the sides of the receptacle, e, and in the space between the stand-pipes, e', and f. An outlet or overflow pipe, 71 communicates with the upper portion of the jacket, f, and the design is to maintain a constant circulation of cold water around the receptacle, e, so that the paint within the same will be subjected to the cooling edect thereof to the best advantage. In order to promote the cooling of the paint, and also keep the same properly mixed, the following means are employed to agitato the paint within the receptacle, e: A shaft, i, operatively connected with the driving mechanism, extends up through the stand-pipe, f', and carries a cross-head, fi', to

the twoopposite ends of whichare aixed pendent arms, 722; -Stirring and scraping blades, 't3 and i, are fastened to the lower ends of the arms, 2, and extend over the in-V clined bottom of the receptacle, e. The said blades are set obliquely and the angle of the blade, i3, is such as to cause said blade under The blade, i, is arranged reversely with krespect to the blade, i3, so that it has the opposite effect on the paint, viz: to`

work the same outwardly from the center of the receptacle. `By this arrangement the paint is thoroughly agitated within the receptacle, e. The blades, 3, and #,scrape overthe bot tom of the receptacle so that dierent portions of the paint are constantly subjected to the cooling eect of the water under the receptacle. The blade, i4, has an upward projecting arm, i5, which extends over the side of the receptaclac, and scrapes the paint therefrom as it revolves, and thus causes different portions ot the paint to be subjected to kthecoolimgf eit'ect of the water surrounding the receptacle. It will be seen thatby the arrangement described.` the paint will be quickly cooled. It is delivered from the receptacle, e, to the barrels,casks, or other receptacles in which it is to be stored throughan outlet which is Y controlled by a gate, j.

Having thus described my invention, what Iclaim as new, and desire` to secure by Letters Patent, is-

l. In a paintmill, a supply funnel having an outlet opening in one side only, a gate controlling egress from said opening, a shaft extending up into thefunnel kand carrying a stirrer-blade, a disk on the shaft and forming a rotating bottom for thefunnel, and a fixed arm projecting from the side of the funnel at one side of the opening and extendingk over the said disk below the plane `ot the stirrer-blade.

2. A paint mill comprising in its construe` tion a supply funnel, a stationary annular receptacle for the paint below said funnel, a waterjacket extendingaround the outersides and under the bottom of said receptacle and connected with a central stand-pipe, an outlet from the paint receptacle through the water jacket and means for agitating the paint In testimony whereof I have signed myk this 19th day ofk
